8 Cessna Aircraft Company CAGE No Page REQUIREMENTS 4.1 Ultrasonic Inspection Producer shall perform the ultrasonic inspection per CSTI006 or AMS-STD-2154, Class A, or per ASTM B594, Class A, on all wrought aluminum alloys listed in Paragraph 3.0 with thickness dimension inch or greater. The producer shall include the ultrasonic certification along with each shipment. 4.2 Tensile Properties Tensile properties shall meet the requirements of the applicable material specification. 4.3 Electrical Conductivity Electrical conductivity tests shall meet the requirements of the applicable material specification. It is permissible to measure the electrical conductivity on the tensile specimens and/or the delivered sheet and plate material in the T temper. 4.4 Chemistry The material shall meet the chemistry requirements of the applicable material specification. 4.5 Polished Aluminum Sheet When required by Cessna Engineering, polished aluminum sheet shall meet the requirements of CMMP Process Control Documents In certain cases, qualified producers listed in this specification have special process or testing requirements documented in an approved Process Control Document (PCD). These cases include, but are not limited to: a. Material Producers using services such as, but not limited to, heat treatment, ingot production, or other special processes outside their facility that affect the properties of the final product. b. Alloys or tempers requiring closer than standard process controls or inspections to ensure consistent properties. c. Other special circumstances. When a PCD is specified, material shall be produced to those requirements, and the producing mill shall include the PCD number on their certification. Producers shall submit PCDs to Cessna M&P Engineering for review and approval. Once approved, no deviations from the PCD are allowed without prior Cessna M&P Engineering approval. 4.7 Certification The producer shall certify that the ultrasonic test results, as required, tensile properties, electrical conductivity, as required, and chemistry meet the applicable material specification for each lot of material supplied in the -T temper. The producer shall also certify that the capability test results of

9 Cessna Aircraft Company CAGE No Page 4 material supplied in the O temper meet the applicable material specification. Certification shall also include any required PCD number. 5.0 MARKING AND IDENTIFICATION Marking and identification shall be per ASTM B666. In addition, the producer shall include ultrasonic inspection marking by stenciling; or with ultrasonic acceptance stamp on each piece in ink or by steel stamp at one end and preferably on both ends. 6.0 QUALITY Controls shall be established to ensure that the requirements of this specification are complied with. 7.0 QUALIFIED PRODUCERS LIST Material per this specification shall only be procured from the producers listed in Tables I and II. 7.1 Approval of a Producer Facility Producers are qualified by facility, the addresses of which are listed in Table III. The facility qualification is not impacted by a producer name change, provided the producer can demonstrate there are no changes to the manufacturing processes, inspection/testing processes, or quality system. Any changes to the manufacturing and/or inspection/testing processes that may affect material properties must be approved by Cessna M&P before implementation. M&P will determine the requalification steps required for approval. -O- and W- temper qualification shall be based on data analysis of capability test results per the applicable material specification. The QPL is an engineering approval. Additional approval by Supply Chain Quality is required prior to material procurement. 7.2 Data Requirements for Statistical Analysis The producer is required to submit sufficient data for each alloy, form and thickness range to establish material properties on a statistical basis. Cessna M&P Engineering will evaluate the data to ensure conformance to design requirements. 7.3 Renewal of Qualifications Cessna M&P Engineering may request an audit and/or data for assessment for renewal of prior approval. The type and quantity of data needed will be communicated to the producer at the time of such request. 7.4 Process Control Documents Process Control Documents (PCD) as defined in section 4.6, when applicable, are shown after the producer s name (For example: PCD-01) in Tables I & II.
